PENCIL-SHABPENER.

Application filed February 18, 1909. Serial No. 478,580.

Specification of Letters Patent.

' Patented Feb. 15, 1910.

To all whom it may concern:

Be it known that I, DWIGHT L. MCBRIDE,

a citizen of the United States, residing at.

functions of a knife and-eraser, that shall be adapted for readyconnection witha lead-pencil, and in such manner as not to add anyobjectionable length thereto, and which shall be simple in construction,efficient and durable in use, andlornamental in appearance.

\Vith the above and other objects in view, as will appear as the natureof the invention is better understood,- the same consists in a novelconstruction and combination of parts of a pencil-sharpener, as willhereinafter be fully described and claimed.

In the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding parts:Figure 1 is a view of a leadpencil equipped with the device of thepresent invention. Fig. 2 is a' View in side elevation, partly insection, showing the pencilsharpener applied to a pencil. Fig. 3 is aperspective detail view of the combined knife and eraser.

Referring to the drawings, 1 designates a lead-pencil, which is hereinshown as polygonal in cross section, although it may be of circularcontour and serve the same purpose. Slidably mounted on one end of thepencil is a sheath 2, which serves to hold the novelty combined with thencil, and also to revent the knife from lnflicting accidenta l injury tothe person carryin it. This is designed to engage the penci withsuflicient frictional grip to retain it and the combined knife anderaser a ainst accidental detachment. The sheat may be either a seamlessor a s lit tube, as preferred, the latter constructlon being, in somecases, advantageous.

The combined knife and eraser comprises a sleeve 3, providedintermediate its ends with a circumferential bead 4:, to limit itsinsertion into the sheath. One end, 5, of the tain a rubber eraser 6properly combined therewith, and the other end 7 is provided with atapering'extension or socket 8, that l is preferably rectangular incross section for the greater portion of its length to receive the tangof the blade or knife 9, which may be of the'style shown or otherwise,as' preferred or found of advantage. The tang may be held in the socketin any preferred manner, either by a rivet, by solder, or by cement, asmay be found most convenient As above pointed out, it is one of theobjects of the invention to obviate'any objectionable increase in thelength of a pencil tipped with the novelty of the present invention, andthis is secured by providing the butt end of the pencil with alongitudinal cleft or slot 10 of suflicientextent to house the blade.The slot will of course be open at its sides, butthis is of no moment,

- asthe sheath extends beyond the cleft end of the pencil and the innerwall of the slot a sufficient distance to prevent any. possibility ofthe knife inflicting injury to the person carryin it. Normally, theknife will be housed wlthin the pencil, thus leaving the eraser exposedfor use, as shown in Fig. 2, but when the knife is required, theposition of the sleeve is reversed to present the knife, as shown inFig. 1. If preferred, the pencil may be dispensed with, and the sheathand combined pencil sharpener and eraser be used as a convenientimplement for ofiice use.

I claim The combination of a pencil having a lon- 'gitudinal slot orcleft in its end, a sheath fitting on the end of the pencil and longerthan said slot, a sleeve fitting within the sheath and provided with acircumferential bead adapted to en age adjacent the end of the same, oneend 0 the sleeve being adapted as my own, I have hereto afiixed mysigna- 105 ture in the presence of two witnesses.
